Ergonomic pillow for neck and upper shoulder muscle release

ABSTRACT

An ergonomic pillow is provided. The ergonomic pillow according to current application is to release muscles of a user&#39;s neck and upper shoulder to remove pains. Office workers usually spend long hours with crouched position. When a user uses this ergonomic pillow while sleeping, it releases muscles on the neck and upper portion of the shoulder of a user. The ergonomic pillow according to current application is comprised of a long cylindrical center portion and two trapezoidal wings whose narrow tip is rounded. The two wings are developed along the long axis of the cylindrical portion on the outer surface thereof. Center portion of one wing is removed for shoulder approach. The pillow of the current application is made of a porous visco-elastic polymer or wood.

1. FIELD OF THE INVENTION

The invention relates generally to a pillow, especially to a pillow that is comprised of a long cylindrical center portion and two trapezoidal wings whose narrow tip is rounded.

2. BACKGROUND

Since a significant amount of attention has been focused on sleeping, particularly how are sleep comfort effects a person's ability to get a good nights sleep, various types of pillows have been produced that minimize or eliminate the problems associated with traditional pillows. Pillow does a critical role in good sleeping. If a user sleeps on a wrong pillow, he/she may not turn the neck next morning. One extreme example is when a user sleep on a stone pillow, the user's may suffer from face muscle monologue. Meanwhile, many people spend long hours with wrong position, such as crouching on a desk for paper work or bend down waist over a work desk for manufacturing. In any position, s/he must bend or stretch neck. After long hours work, his/her neck get stiff and sometimes get pain. On the other hand, seniors or people with high blood pressure always feel that their neck is stiff. Massaging the neck may release the feeling of the stiffness. But, that is only temporary. Therefore, a novel and cheap method or tool for releasing the muscle and pain everyday is needed. Inventor of the current application focused that pillow is the only tools that everybody use everyday and contact the neck and upper shoulder. Pillow of a novel design shown in the current application release muscle and pain effectively.

SUMMARY OF THE INVENTION

Since a significant amount of attention has been focused on sleeping, various types of pillows have been produced that minimize or eliminate the problems associated with traditional pillows. Pillow does a critical role in good sleeping. If a user sleeps on a wrong pillow, for example, on a stone pillow, the user may suffer from face muscle monologue. Meanwhile, many people spend long hours with wrong position, such as crouching on a desk for paper work or bend down waist over a work desk for manufacturing. In any position, s/he must bend or stretch neck. After long hours work, his/her neck get stiff and sometimes get pain. On the other hand, seniors or people with high blood pressure always feel that their neck is stiff. Massaging the neck may release the feeling of the stiffness. But, that is only temporary. Therefore, a novel and cheap method or tool for releasing the muscle and pain everyday is needed. Inventor of the current application focused that pillow is the only tools that everybody use everyday and contact the neck and upper shoulder. To realize the goal an ergonomic pillow is provided. The ergonomic pillow according to current application is to release muscles of a user's neck and upper shoulder to remove pains. Office workers usually spend long hours with crouched position. When a user uses this ergonomic pillow while sleeping, it releases muscles on the neck and upper portion of the shoulder of a user. The ergonomic pillow according to current application is comprised of a long cylindrical center portion and two trapezoidal wings whose narrow tip is rounded. The two wings are developed along the long axis of the cylindrical portion on the outer surface thereof. Center portion of one wing is removed for shoulder approach. The pillow of the current application is made of a visco-elastic polymer or wood.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

The ergonomic pillow for neck and upper shoulder muscle release is designed not only for releasing muscle and pains but also good in terms of hygiene. The FIG. 1 is a perspective view of a pillow (1) according to current invention. The pillow has a cylindrical center portion (2) and two wings (3), (4). One wing (3) is longer than the other wing (4). An air hole (5) is developed throughout the whole horizontal width (6) of the pillow. The air hole (5) allows air to pass through to remove sweats from the pillow (1) while a user (7) sleeping. The air hole (5) also facilitates penetration of water and detergent through the pillow (1) when doing a laundry. Center portion (4-2) of shorter wing (4) is removed for shoulder approach. Horizontal width (6) of the pillow (1) is in the range of 50 cm to 100 cm depending on the gender and age of a user. Vertical length (8) of the pillow (1) is in the range of 33 cm to 60 cm. Outer diameter (9) of the center portion (2) is in the range of 5 cm to 10 cm. Diameter (10) of the air hole (5) is in the range of 1 cm to 3 cm. Length of one wing (3) from the center of the center portion (2) is in the range of 16 cm to 45 cm. Width (11) of the center portion (4-2) of the shorter wing (4) is in the range of 12 cm to 18 cm.

The pillow (1) according to current invention is made of a porous visco-elastic polymer, porous poly-urethane for example, or porous wood, cork for example. A tube type insert (12) is engaged to the air hole (5) when the pillow is made of a porous visco-elastic polymer. The insert (12) is made of flexible PVC (poly-vinyl chloride) with pluralities of small holes (13) of average diameter 3 mm. The tube type insert (12) supports the air hole (5) of the pillow (1) to maintain air flow there through.

FIG. 2 is a side view of the pillow (1) according to current invention. Side view of the pillow (1) is well curvature. The center portion (2) is basically circle shape. The center portion (2) and wings (3), (4) meet and for concave surfaces (14). Tips (3-1), (4-1) of each wings (3), (4) are rounded.

FIG. 3 is a side view of a user (7) lying on the pillow (1) according to current invention. When a user lies on the pillow (1), the cervical vertebrae (15) of the user (7) are stretched along the curvature of the center portion (2). Stiffness of the pillow (1) is adjusted by controlling stiffness of the insert (12). Upper shoulder (16) of the user (7) is pressed by the rest (4-3) of the wing (4).

By stretching the cervical vertebrae (15) of the user while pressing the upper shoulder (16), the ergonomic pillow (1) releases muscles surrounding the cervical vertebrae (15) and the upper shoulder (16)
